Oxydendrum arboreum, Sourwood Cricket Hill Garden

Variety description: This outstanding native tree has many attributes which make a fine addition to the landscape. Commonly called sourwood or sorrel tree, Oxydendrum is a deciduous understory tree that is native to the eastern United States from Pennsylvania south to Florida and Louisiana.

Gray bark on mature trees is fissured, ridged and scaly. Finely-toothed, glossy green leaves (to 5-8” long) are reminiscent of peach. Leaves have a sour taste, hence the common name. Leaves produce consistently excellent fall color, typically turning crimson red. Waxy, lily-of-the-valley-like, white flowers bloom on slender, drooping, one-sided terminal panicles (4-8” long) in early summer. Flowers have a slight fragrance. Flower panicle stems remains in place as the flowers give way to 5-parted dry capsules that ripen to silver-gray in September. Capsules contrast well with the red fall color and provide continuing ornamental interest after leaf drop into winter. Flowers are quite attractive to bees.
